Wwwwwelllllllll.........I am going to be putting on a supercharger next year so it will need to handle 250-300kw's at the flywheel.
I dont do burnouts (often) but I do like to give it a bit off the lights when needed, so I can say that I do drive sedately most days but it will need to handle an occasional flog every now and then!

Will a supra 5 speed with the right bell housing be a straight conversion or is that going to be to much mucking around?

Reason why I'm asking is that I reckon I could release another 20rwkw or so by the manual conversion and if that is done with minimal fuss, it may be worth the investment. My auto 4 speed sucks a heap of power to the wheels its almost embarrasing!
I am currently getting 115rwkw atm and feel that a manual conversion will get me closer to 130rwkw before the supercharger goes on. It will just depend on if it will be worth the root around and the cash in the end!

Supra 5 speed will fit wit minimal fuss, but becarefull about which box it is...From memory I think there is a N/A version and turbo version. turbo version was much stonger internally than the NA. (correct me if I'm wrong anyone) As for telling the difference, good luck, they look the same! Talk to Dellow conversions they should be helpful.

EA box will NOT fit and WILL NOT be strong enough anyway. You would be better off getting a V8 T5. You will have to change heaps of stuff to go to a supra, and a turbo supra will cost more than a V8 T5. If you get it in Sydney, it will probably be a turbo hilux box anyway.

EA box is basically the same, I am assured it is strong enough.
However, the input shaft on the 6 box is a lot shorter, you would have to change that. My 2 cents: If ya going to boost it, play it safe and get the v8 box :)

Yes, the only differences are the input, the cluster, first, second, third, fifth driver and fifth driven gears. As you intend to supercharge it, for long term reliability you will need to run T5Z internals, at which point the mainshaft will also be different. The EA box runs a 22tooth input shaft, a longer version of this is not available. V8 boxes run a 24tooth input. If you get a shorter bellhousing, then the shifter position, crossmember and tailshaft will all be wrong.
